SGRAPER FOR ROAD-ENGINE WHEELS.

T 0 all whom it may concern:

Be it known that I, GUSTAF ARVID ANDER- sort, a citizen of the UnitedStates, residing at lVaynesboro, in the county of Franklin and State ofPennsylvania, have invented certain new and useful Improvements inScrapers for Road-Engine Wheels; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to scrapers for removing dirt from the mainroad-wheels of road-rollers; and it consists in the novel constructionand combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a side view of portions of a road-rollershowing the scrapers. Fig. 2 is a side view of the front scraper drawnto a larger scale. Fig. 3 is an end view of the front scraper.

A is a stationary support, such as the frame or boiler of a road-roller.

B is one of the main road-wheels of the road-roller, which is mounted torevolve on an axle Z) carried by the said support.

C is a holder for the front scrapenblade c. The upper end portion of theholder C is pivoted to the support A by a pin 0, and the scraper-blade 0is secured to its lower end portion so that its edge ean bear at asuitable angle against the periphery of the wheel B.

I) is a shaft which is journaled in a bearing (Z formed on the middlepart of the holder C. An arm E is rigidly secured on one end of theshaft D, and projects downward; and an arm F is rigidly secured on theend of the shaft D and projects upward.

G is an arm for the rear scraper having the rear scraper-blade g securedto its lower end portion and arranged to bear against the periphery ofthe road-wheel on the other side of its shaft from the scraper-blade c.The arm G is pivoted to the support A by a pin 9 I A coupling-rod e ispivoted to the arm G and the arm E by pins 6.

H is an operating-lever which is mounted loose on one end'portion of theshaft D adj acent to the arm F which projects upward, and the arm F isprovided at its free end with a lug or cup f which overlaps the lever H.

I is a pin which is pivoted to the lever I'I Specification of LettersPatent. 1 Application filed December 20, 1909. Serial No. 534,042.

bya pin it and which has a plate ?I on its free end portion. A coiledsprlng z" is interposed between. the lug f and plate 2', andnorconnected with the lever H and engaging with the notchedquadrant-plate. Stops 7c are provided on the support A to prevent thescraper-blades frombeing moved too far away from the wheel, and toprevent them from vibrating.

In moving the operating-lever pivotally toward the wheel to apply thetwo scrapers, the spring bears against the arm F and operates theshaft'l). The arm E on the shaft D operates the rear scraper by means ofthe coupling-rod, and the rear scraperblade 9 is pressed against thewheel. As soon as the blade 9 bears against the wheel, the continuedmotion of the operating lever lifts the front scraper-blade intoengagement with the wheel, the scraper holder (1 being turned on itspivot c. The two scraper-blades are held in engagement with the wheel bythe pressure of the spring 2" so that they adapt themselves to slightirregularities on its surface. As the blades become worn away it isnecessary to move the operatin -lever to a different position, and thequadrant-plate is provided with a series of notches for holding theoperating-lever in different positions.

lWhen the operating-lever is unlocked from the quadrant-plate and movedpivotally away from the wheel, the said lever bears against the lug fand turns the shaft D backward, and both scraper-blades are then movedaway from the wheel by the operating-lever and by gravity. Thescraperblades can be held in against the wheel by the quadrant-plate andcatch, or they can be allowed to rest against their stops. When spursare inserted in the road wheels, either to climb a hill-or to tear up anold road, the scrapers are held. against the stops so that they cannotvibrate and are always clear of the spurs. If the stops were not,provided the scrapers would oscillate when the roller is started andstopped suddenly, and would be injured by contact with the spurs.

What I claim is:

1. The combination, with a support, and a road-wheel; of ascraper-holder pivoted to the said support and provided with ascraper-blade, a shaft journaled in the said scraperholder and havingtwo arms secured on it, means for coupling one of the said arms with thesaid support, and an operating-lever mounted loose on the said shaft andoperatively connected with the other arm.

2. The combination, with a support, and a road-wheel; of a scraperholder pivoted to the said support on one side of the roadwheel andprovided with a scraper-blade, a shaft journaled in the middle part ofthe said holder and having two arms secured on it, a scraper pivoted tothe support on the other side of the road-wheel, a coupling rod betweenthe said scraper and one of the said arms, and an operating-levermounted loose on the said shaft and operatively connected with the otherarm.

3. The combination, with a support, and a road-wheel; of ascraper-holder pivoted to the said support and provided with ascraper-blade, an arm pivoted to the said scraper-holder, means forcoupling the said arm with the said support, an operatinglever alsopivoted to the said scraper-holder, and connecting devices interposedbetween the said operating-lever and arm, whereby the scraper-blade ispressed against the roadwheel when the operating-lever is moved in onedirection.

l. The combination, with a support, and a road-wheel; of a scraperholder pivoted to the said support on one side of the roadwheel andprovided with a scraper-blade, a shaft journaled in the middle part ofthe said holder and having two arms secured on it, a scraper pivoted tothe support on the other side of the road-wheel, a coupling-rod pivotedto the said scraper-holder, means for coupling the said arm with thesaid support, an operating-lever also pivoted to the saidscraper-holder, connecting devices interposed between the said lever andarm, and catch-mechanism for locking the operating lever to the saidholder and thereby retaining the scraper in engagement with. the saidstop when desired.

6. The combination, with a support provided with stops, and a roadwheel; of a scraper-holder pivoted to the said support on one side ofthe road wheel and provided with a scraper-blade, an operating-leveralso pivoted to the said scraper-holder, connect ing devices interposedbetween the said lever and arm, a scraper pivoted to the support on theother side of the road wheel, a coupling device between the last saidscraper and the said arm, and catch-mechanism for locking theoperating-lever to the said scraper holder and thereby retaining thescrapers in engagement with the said stops when desired.

In testimony whereof I have aflixed my signature in the presence of twowitnesses. GUSTAF ARVID ANDERSON. Witnesses DANIEL S. BEARD. H. E.KUHNER.
